Name the property illustrated by the following. explain.
a. x + (-x) = 0

b. x + (-y) = -y + x

simplify. explain.
8+ (-8) + a

x + (-5) + 1

-9 = m = (-6)

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
